According to the invention, an actuable shut-off device (7) is provided which shuts off the bottom outlet chamber port (6). By this means, a particularly simple construction of the fat separator is achieved. <IMAGE>

Description

Die Erfindung betrifft einen mindestens zweischichtig arbeitenden Abscheider, insbesondere einen Fettabscheider , insbesondere gemäß DIN 4040 mit einem Zulaufraum, gegebenenfalls einem integrierten oder einem externen Schlammabscheideraum, einem Fettabscheideraum und einem eine untere Ablaufraumöffnung aufweisenden Ablaufraum, der zwischen dem Fettabscheideraum und dem Ablauf des Fettabscheiders angeordnet und durch eine Tauchwand vom Fettabscheideraum abgetrennt ist.The invention relates to a separator working at least in two layers, in particular a grease separator, in particular in accordance with DIN 4040 with an inlet space, optionally an integrated or an external sludge separator space, a grease separator space and an outlet space having a lower outlet space opening, which is arranged between the fat separation space and the outlet of the fat separator and is separated from the grease separating area by a baffle.

Fettabscheider sind regelmäßig zu entsorgen. Nach dem Entsorgen ist der Fettabscheidebehälter zunächst wieder mit Wasser zu befüllen, bevor der erneute Zulauf des fetthaltigen Abwassers beginnt. Sofern Trinkwasser dazu verwendet wird, ist nach DIN 1988 vorgeschrieben, eine sogenannte Freifallstrecke vorzusehen, was die Wiederbefüllanlage verkompliziert. Außerdem ist die Verwendung von Trinkwasser zum Wiederbefüllen relativ teuer.Grease traps must be disposed of regularly. After disposal, the grease separator tank must be filled with water again before the grease-containing wastewater starts to flow again. If drinking water is used for this purpose, DIN 1988 requires that a so-called free-fall section be provided, which complicates the refilling system. In addition, the use of drinking water for refilling is relatively expensive.

Im DE-GM 90 03 226 wird gefordert, dem Abscheider einen Sammelbehälter für gereinigtes Wasser nachzuschalten und den Sammelbehälter mit einer Pumpenanlage und einem zusätzlichen Füllanschluß mit Freifallstrecke für Frischwasser auszurüsten. Eine solche Anlage reduziert zwar den Frischwasserverbrauch, ist aber sehr aufwendig und erfordert erheblichen Bauraum.DE-GM 90 03 226 requires that the separator be followed by a collecting tank for purified water and to equip the collecting tank with a pump system and an additional filling connection with a free-fall section for fresh water. Although such a system reduces fresh water consumption, it is very complex and requires considerable installation space.

Aufgabe der Erfindung ist, den Aufbau eines Fettabscheiders bezüglich der Wiederbefülleinrichtungen erheblich zu vereinfachen.The object of the invention is to considerably simplify the construction of a fat separator with regard to the refilling devices.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung werden in den Unteransprüchen gekennzeichnet. Anhand der in der Zeichnung dargestellten Beispiele wird die Erfindung im folgenden näher erläutert. Es zeigen:

Fig. 1 bis 3
schematisch und in der Seitenansicht Fett-abscheider mit verschiedenen Absperreinrich-tungen für den Ablaufraum, und

schematisch eine weitere Ausführungsform der Absperreinrichtung in Seitenansicht (Fig. 4 und 5) sowie in Draufsicht.
This object is solved by the features of claim 1. Advantageous developments of the invention are characterized in the subclaims. The invention is explained in more detail below with reference to the examples shown in the drawing. Show it:
1 to 3
schematic and in side view grease separator with various shut-off devices for the drainage chamber, and
4 to 6
schematically another embodiment of the shut-off device in side view (Fig. 4 and 5) and in plan view.

Vom üblicherweise aufgebauten Fettabscheider mit DurchlaufFunktion ist in den Fig. 1 bis 3 lediglich der Abscheidebehälter 1 mit dem Fettabscheideraum 1a, der Zulauf 2 und der Ablaufraum 4 mit Ablauf 3 und Tauchwand 5 dargestellt. Alle übrigen üblichen Bestand- bzw. Bauteile eines Fettabscheiders sind nicht abgebildet, weil sie für das Verständnis der Erfindung unwesentlich sind.Of the usually constructed grease separator with a continuous function, only the separating container 1 with the grease separating chamber 1 a, the inlet 2 and the outlet chamber 4 with the outlet 3 and baffle 5 are shown in FIGS. 1 to 3. All other usual components of a grease separator are not shown because they are not essential for understanding the invention.

Wesentlich ist, daß die in Bodennähe des Abscheidebehälter 1 vorgesehene Ablaufraumöffnung 6 mit einer Absperreinrichtung 7 ausgerüstet ist, die selbsttätig oder von außen von Hand oder automatisch bzw. motorisch betätigbar ausgebildet ist. Mit dieser Absperreinrichtung 7 kann die Öffnung 6 abgedichtet bzw. verschlossen werden.It is essential that the drain space opening 6 provided near the bottom of the separating container 1 is equipped with a shut-off device 7 which is designed to be operated automatically or externally by hand or automatically or by motor. The opening 6 can be sealed or closed with this shut-off device 7.

Aufgrund der Absperreinrichtung 7 erübrigt sich ein Wiederbefüllen des Fettabscheiders nach der Entsorgung und bevor der Zulauf 2 wieder geöffnet wird. Bei verschlossener Ablaufraumöffnung 6 kann der Zulauf 2 nach dem Entleeren des Fettabscheideraums 1a wieder geöffnet und das Abwasser in den Behälter 1 eingelassen werden, bis der Abwasserspiegel höher gestiegen ist als die Ablaufraumöffnung 6 positioniert ist. Danach kann die Absperreinrichtung 7 betätigt und die Ablaufraumöffnung 6 wieder freigegeben werden. Der richtige Zeitpunkt für das Öffnen der Ablaufraumöffnung 6 kann durch Füllstandanzeiger (nicht dargestellt) angezeigt werden; Schaltelemente mit Stellelementen (nicht dargestellt) verstellen dann die Absperreinrichtung 7.Due to the shut-off device 7, there is no need to refill the grease separator after disposal and before Inlet 2 is opened again. When the drain chamber opening 6 is closed, the inlet 2 can be opened again after the grease separating chamber 1 a has been emptied, and the waste water can be let into the container 1 until the waste water level has risen higher than the drain chamber opening 6 is positioned. The shut-off device 7 can then be actuated and the drain space opening 6 can be released again. The correct time for opening the drain space opening 6 can be indicated by level indicators (not shown); Switching elements with adjusting elements (not shown) then adjust the shut-off device 7.

Nach einer einfachen und zweckmäßigen Ausführungsform der Erfindung (Fig. 1) weist die Absperreinrichtung 7 eine z.B. an der Tauchwand 5 gelenkig angeordnete Absperrklappe 8 auf, deren Form und Größe so gewählt ist, daß sie die Ablaufraumöffnung 6 versperren kann. Die Absperrklappe 8 steht mit einem am unteren Gelenk 9 angeordneten, nach oben gerichteten Gestänge 10 in Verbindung, das an einem oberen, z.B. der Tauchwand 5 sitzenden Gelenk 11 endet. Am oberen Gelenk 11 ist ein Schwimmer 12 mit Schwimmersteg 13 befestigt. Der Schwimmer 12 mit Schwimmersteg 13 ist in Doppelpfeilrichtung 14 schwenkbar, wobei die Schwenkbewegung in an sich bekannter Weise mit einer entsprechenden Hebeleinrichtung (nicht dargestellt) auf das Betätigungsgestänge 10 übertragen wird, das wiederum über eine entsprechende Hebelanordnung (nicht dargestellt) die Schwenkbewegung der Absperrklappe 8 in Doppelpfeilrichtung 15 bewirkt. Die Absperrklappe 8 ist nach dem Entleeren des Abscheidebehälter 1 gegen die Ablaufraumöffnung 6 gedrückt; der Schwimmer 12 befindet sich in der unteren Stellung (gestrichelt gezeichnete Darstellung). Der Zulauf 2 kann geöffnet werden; das Abwasser steig im Fettabscheideraum 1a auf, kann jedoch noch nicht in den Ablaufraum 4 gelangen. Wenn das Abwasser den Schwimmer 12 erreicht und höher steigt, wird der Schwimmer 12 mit Schwimmerstange 13 verschwenkt bzw. geöffnet, so daß fettfreies Abwasser in den Ablaufraum 4 gelangt und der Fettabscheider seine Durchlauf-Funktion aufnimmt. Das Gelenk 9 kann auch an der Rückwand des Fettabscheideraums angeordnet sein, so daß die freie Endkante der Klappe 8 über die Tauchwand 5 hinausragt (nicht dargestellt). An der freien Endkante ist in diesem Fall gelenkig das Gestänge 10 angeordnet.According to a simple and expedient embodiment of the invention (FIG. 1), the shut-off device 7 has a shut-off flap 8, which is articulated, for example, on the baffle 5, the shape and size of which is selected such that it can block the outlet space opening 6. The butterfly valve 8 is connected to an upwardly directed linkage 10 which is arranged on the lower joint 9 and ends at an upper joint 11, for example the diving wall 5. A float 12 with a float web 13 is attached to the upper joint 11. The float 12 with the float web 13 can be pivoted in the double arrow direction 14, the pivoting movement being transmitted in a manner known per se to the actuating linkage 10 using a corresponding lever device (not shown), which in turn uses a corresponding lever arrangement (not shown) to pivot the butterfly valve 8 causes in the double arrow direction 15. The shut-off valve 8 is pressed against the drain space opening 6 after the separating container 1 has been emptied; the float 12 is in the lower position (dashed line). The inlet 2 can be opened; the wastewater rises in the grease separating chamber 1a, but cannot yet reach the outlet chamber 4. When the waste water reaches the float 12 and rises higher, the float 12 is pivoted with the float rod 13 or opened so that grease-free wastewater enters drain chamber 4 and the grease separator begins its continuous function. The joint 9 can also be arranged on the rear wall of the grease separating space, so that the free end edge of the flap 8 projects beyond the baffle wall 5 (not shown). In this case, the linkage 10 is articulated on the free end edge.

Anstelle einer mit einem Schwimmer betätigten Klappe 8 kann man motorisch betriebene Klappen oder Schieber als Absperreinrichtung gemäß den Fig. 2 und 3 verwenden.Instead of a flap 8 actuated by a float, motor-operated flaps or slides can be used as a shut-off device according to FIGS. 2 and 3.

In Fig. 2 ist ein Schieber 16 angedeutet, der in horizontaler Richtung (Doppelpfeil 17) verschiebbar ist. Ein solcher Schieber kann auch gemäß Doppelpfeilrichtungen 18,19 verschiebbar angeordnet und entweder von Hand oder motorisch oder magnetisch antreibbar ausgebildet sein (nicht dargestellt).In Fig. 2, a slide 16 is indicated, which is displaceable in the horizontal direction (double arrow 17). Such a slide can also be arranged displaceably in accordance with double arrow directions 18, 19 and can be designed to be driven either by hand or by motor or magnet (not shown).

In Fig. 3 ist eine Absperrglocke 20 angedeutet, die von Hand oder motorisch oder magnetisch in Doppelpfeilrichtung 21 verschiebbar eingerichtet ist.In Fig. 3, a shut-off bell 20 is indicated, which is designed to be movable by hand or by motor or magnetically in the double arrow direction 21.

In den Fig. 4 bis 6 ist eine weitere bevorzugte Variante der Absperreinrichtung gezeigt, die sich durch einen besonders einfachen und funktionstüchtigen Aufbau auszeichnet. Erreicht wird dies dadurch, daß die Absperrklappe 8 starr mit einer Schwimmereinrichtung 22 verbunden ist, wodurch ein Steuergestänge wie in Fig. 1 entfallen kann.4 to 6 show a further preferred variant of the shut-off device, which is distinguished by a particularly simple and functional structure. This is achieved in that the butterfly valve 8 is rigidly connected to a float device 22, whereby a control linkage as in Fig. 1 can be omitted.

Die Absperrklappe 8 ist bei dieser Variante der Absperreinrichtung in Art eines Schwingdeckels ausgelegt, vermag also nur um eine Achse, im dargestellten Ausführungsbeispiel um die Längsmittelachse 23 zu verschwenken oder zu schwingen. Aufgrund dieser Schwinglagerung befindet sich also stets eine der beiden Absperrklappen-Längskanten 24, 25 über der anderen Längskante, abgesehen von der "Gleichgewichtslage" der Absperrklappe 8, die beim gezeigten Ausführungsbeispiel niemals eingenommen wird, weil einander gegenüberliegende, an der Fettabscheiderrückwand 26 und an der Tauchwand 5 angeordnete Anschlagkisten 27 und 28 nicht unterschiedliche Höhenpositionen einnehmen, so daß die Absperrklappen-Längskante 24 bzw. 25 an der Anschlagkiste 27 bzw. 28 zur Anlage kommt, während die Absperrklappe 8 noch eine leicht schräge Position einnimmt, die von der Horizontalen abweicht. Alternativ hierzu können die Anschlagleisten 27 und 28 auch so angeordnet sein, daß die Absperrklappe 8 in der Schließstellung, in der ihre Längskante 24, 25 im Eingriff mit den Anschlagleisten 27,28 stehen, im wesentlichen waagrecht ausgerichtet ist. Die Anschlagleisten 27, 28 erstrecken sich über die gesamte Länge der Absperrklappe 8, um deren Dichtungs- oder Absperrwirkung zu gewährleisten.In this variant of the shut-off device, the butterfly valve 8 is designed in the manner of a swinging lid, so it can only pivot or swing about an axis, in the exemplary embodiment shown about the longitudinal central axis 23. Because of this vibration bearing there is always one of the two butterfly valve longitudinal edges 24, 25 above the other longitudinal edge, apart from the "equilibrium position" of the butterfly valve 8, which is never assumed in the exemplary embodiment shown, because opposing stop boxes 27 and 28 arranged on the grease separator rear wall 26 and on the baffle wall 5 are not assume different height positions, so that the butterfly valve longitudinal edge 24 or 25 comes to rest against the stop box 27 or 28, while the butterfly valve 8 still occupies a slightly oblique position which deviates from the horizontal. As an alternative to this, the stop bars 27 and 28 can also be arranged such that the shut-off flap 8 is oriented essentially horizontally in the closed position, in which its longitudinal edge 24, 25 are in engagement with the stop bars 27, 28. The stop strips 27, 28 extend over the entire length of the butterfly valve 8 in order to ensure its sealing or shut-off effect.

Die Schwimmereinrichtung 22 ist also starr mit der Absperrklappe 8 verbunden. Zu diesem Zweck ist die Schwimmerstange 29, deren eines Ende den Schwimmer 30 trägt, fest mit der Absperrklappe 8 verbunden, und zwar in unmittelbarer Nähe der Absperrklappen-Schwenk- oder Schwingachse 23 bzw. direkt mit dieser. Die Schwimmerstange 29 verläuft unter einen vorgegebenen Winkel zur Absperrklappe 8, der so gewählt ist, daß der Schwimmer 30 bei vollständig geöffneter Absperrklappe 8 bei gefülltem Fettabscheideraum an der diesem zugewandten Seite der Tauchwand 5 oberhalb der Leisten 27, 28 zur Anlage gelangt, während der Schwimmer 30 bei vollständig geschlossener Absperrklappe 8 unterhalb dieser zu liegen kommt und dadurch die Längskanten 24, 25 gegen die Leisten 27, 28 preßt und einen hinreichenden Verschluß des Ablaufraums 4 sicherstellt.The float device 22 is thus rigidly connected to the butterfly valve 8. For this purpose, the float rod 29, one end of which carries the float 30, is firmly connected to the butterfly valve 8, in the immediate vicinity of the butterfly valve pivoting or swinging axis 23 or directly with the latter. The float rod 29 extends at a predetermined angle to the butterfly valve 8, which is selected so that the float 30 comes to rest when the butterfly valve 8 is fully open with the grease separating space on the side of the baffle 5 facing this above the strips 27, 28, while the float 30 when the butterfly valve 8 is completely closed, it lies below it and thereby presses the longitudinal edges 24, 25 against the strips 27, 28 and ensures an adequate closure of the outlet space 4.

Aus der Draufsicht von Fig. 6 geht hervor, daß die Schwimmerstange 29 im Bereich einer Schmalseite der Absperrklappe 8 an dieser befestigt ist.6 shows that the float rod 29 is fastened to the butterfly valve 8 in the region of a narrow side of the latter.

Die Fig. 1 bis 5 zeigen beispielhaft Absperreinrichtungen 7. Der Fachmann wird nach Kenntnis der vorliegenden Erfindung weitere Absperreinrichtungen auffinden können, wenn er von der verblüffend einfachen Lösung erfährt, bei einem Fettabscheider ohne Nachfülleinrichtungen auszukommen. Die Erfindung schließt nicht aus, Nachfülleinrichtungen in Kombination mit der erfindungsgemäßen Absperreinrichtung zu verwenden, weil auch die Kombination erhebliche Vereinfachungen beim Betrieb eines Fettabscheiders bringt.1 to 5 show shut-off devices 7 by way of example. The person skilled in the art will be able to find further shut-off devices to the knowledge of the present invention if he learns of the astonishingly simple solution to do without refill devices in a grease separator. The invention does not rule out the use of refill devices in combination with the shut-off device according to the invention, because the combination also brings about considerable simplifications when operating a grease separator.
